The security torx bit is made of S2 alloy steel, the hardness is as high as HRC60±, the high-temperature quenching treatment is durable, the surface is nickel-plated, and has good anti-rust and anti-corrosion functions. Security bits and drivers are used with security screws to create secure fastener assemblies. They can be used anywhere that tampering might be suspected. Such as repairs, interiors, computers, electronics, etc. The 1/4" hex handle can be used with electric screwdrivers, hand screwdrivers, power drills, combination utility tools, and any standard drill bit. Notice: Do not turn screws that do not match the size to prevent damage to the screw and bit.
